Volkswagen Group (UK) has signed a partnership deal with green energy supplier Ecotricity to provide a 100% green energy offer to all customers buying one of its electric-powered vehicles.

The group recently announced that it has its sights set on market leadership in electric mobility by 2018.

The deal means any customer buying an electric vehicle from one of the group's brands will be offered, at point of sale, the option to adopt Ecotricity's 100% green tariff for their home and vehicle energy supplies.

When Ecotricity was founded in 1995, it became the world's first 'green electricity' company. Its aim is to change the way electricity is made and used in Britain.

Now powering more than 75,000 homes and businesses from its growing fleet of wind and sun parks, Ecotricity is a 'not-for-dividend' enterprise that, on average, invests more per customer in building new sources of green electricity than any other energy company in Britain.

The first Volkswagen Group electric car to go on sale in the UK will be the Volkswagen e-up! city car. Order books will open next month with the first deliveries in January. On sale mid-2014 will be the e-Golf, followed at the end of the year by the Audi A3 Sportback e-tron plug-in hybrid.
